SPECIFICATION forming part of Letters Patent No. 447,621, dated March 3, 1891.

Application filed March 22,1890. $eria1No. 344,922. (ModeL) T0 at whom it may concern.-

Be it known that we, THOMAS A. PHILLIPS and JAMES J. GREENHOE, of Williamstown, in the county of Dauphin and State of Pennsylvania, have invented a new. and Improved Look, of which the following is a full, clear,

and exact description.

Our invention relates to improvements in looks; and the object of our invention is to provide a safe and reliable look by means of which a door may be fastened, and also to provide a lock that may be used without a key, and that may be arranged from the inside of a building or room in such a manner that it is impossible to operate it from the outside.

To this end our invention consists in a lock constructed substantially as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the lock with a side of the case removed and the bolt drawn into the case; Fig. 2, the same view,but with the bolt thrown out and locked in that position; Fig. 3, a vertical transverse section of the look as applied to a door, the section being taken on the line m of Fig. 2; Fig. 4, a side elevation of the outside of the lock; Fig. 5, an end view of the same; Fig. 6, a side elevation of the sliding frame and bar which moves in the lock-case; Fig. 7, a vertical cross-section on the line 2 of Fig. 6; Fig. 8, a transverse section on the line y 1 of Fig. 2 3 Fig. 9, a plan of the sliding frame and bar; Figs. 10 and 11, details of a stop for setting the lock for day use; Figs. 12 and 13, details of the locking-stop Fig. 14-, a detailed view of the lock-spindle with the tumbler thereon; Fig. 15, an end View of the same; Fig. 16, a side elevation of one of the lock-disks with an operating-knob attached, and Fig. 17 a plan of the same.

The lock has a rectangular case A, which is provided with a suitable cap A, and is attached to the inside of a door E in the usual manner. Within the caseAis a horizontallymovable frame B, having a recess Btherein, in which the tumbler 0 may be moved, and

through which the disks D D may be connected, and having one end thereof formed into a locking-bar B The frame B is also provided with a thinned portion B against which the disks D D rest, said portion being thin enough to allow the disks to turn freely between said portion and the side of the case A and cap A. v

Upon the upper edge of the frame B is a rectangular slot or recess B in which the stop a may be inserted to limit the movement of the frame, a rectangular slot or recess B which extends to the thinned portion B of the frame B and allows the arms of the stop I) to lie close to said thinned portion, and upon each side of the frame, near the open end of the case A, is 'a horizontal rib B, which may move in the radial slots 0 of the disks D D. The stop a is provided at the top with a knob a by which it may be raised into the slot a of the case A, so as to permit a free movement of the frame B within the case.

A two-armed stop Z2, which projects through the case A and has a limited vertical movement therein, and has a suitable knob 11 attached to the upper end thereof, straddles the frame B in the recess 13, and each arm thereof extends downwardly, so as to project between the slots 0 of the disks D D and the ribs B of the frame B when the door is looked, as shown in Fig. 2. The frame B and bolt or bar B are held normally in locked position by the spring F, which presses against the back end of the frame B and the inner back end of the case A.

The tumbler O is of oblong shape and is fixed to the lock-spindle C, which passes through the case A and cap A, and is provided with the usual knobs C so that by turning a knob the tumbler will be turned against the frame B at the rear end of the recess B and will retract the frame and locking-bar.

The disk D is pivoted on the cap A by the pin d, which projects through the cap and door E, and is provided on the outside with a knob d, by which the pin and disk may be turned. The disk D is provided with a radial slot 0, to receive one of the ribs B and with an inwardly-projecting catch e, which is attached to the inner side of the disk, and which is diametrically opposite the slot 0.

The disk D is of the same size as the disk D, is pivoted on the case A Opposite the disk D by the pin f, which projects through the case, and is provided at the outer end with a knob f, by which it and the disk D may be turned. The disk D is also provided with a radial slot 0 to receive one of the ribs B and upon its inner side, at right angles with the slot a, is a pin g, which is fixed to the disk and is the same distance from the center of the disk as the catch a from the center of the disk D, so when either the disk D or D is turned the catch 6 and pin Q will strike each other.

Upon the outside of the door l*1,around the pin (Z, and upon the outside of the case A, around the pinf, is a numbered scale it, like that of the ordinary combination-lock, though letters or other distinguishing marks may be used.

The lock is operated as follows: For ordinary day use the stop a is forced into the recess 13' of the frame 13, and as the recess B is shorter than the ribs 13'' the lower ends of the stop D will rest upon the ribs, as shown in Fig. 1, as the frame cannot move far enough for the stop to be pushed between the disks D D and the ribs Consequently the frame B and locking-bar ll may be freely moved far enough to open and close the door by the tumbler C and knobs C When used as a lock which may be opened from the outside or inside of the door, both the stops a and Z) are raised and the spring F will normally hold the frame l3 and locking-bar B in locked position, and the disks D D will prevent the frame from being moved by the knobs 0 as the ribs B will strike against the edges of the disks. The door is unlocked from the outside as follows: As shown in the drawings, when a part on the knob (1 (indicated by an arrow) is opposite the number 3 on the scale-plate h the slot 0 of the disk D will be in line with the ribs 13", and it is known that the catch 6 is diametrically opposite said slot. It is also known that'when the slot 0 of the disk D is opposite one of said ribs the pin 9 will be at right angles with said slot. The disk D is therefore turned to the right by the knob d till the catch 6 strikes the pin g. It is then turned till the arrow is opposite the figure 6. This will bring the slot 0 of the disk D opposite one of the ribs 13 The knob (Z is then turned to the left till the arrow is opposite the numher 3 on the plate 72, and this will bring the slot 0 of the disk D opposite the other rib 13 Both the slots 0 will then be in line with the ribs B and by means of the knobs C and tumbler (J the bolt 13 may then be thrown, as

the ribs B will slide in the slots 0 of the disks 1) D. It is obvious that the disks may be attached to the pins in such a manner that they will operate when opposite any desired number.

To set the look from the inside so that it cannot possibly be opened from the outside, the stop a is raised and the stop Z) pushed downwardly till the arms come between the ends of the ribs 13 and the disks I) D. It will thus be seen that when the slots 0 are in line with the ribs 13 the bolt cannot be thrown, and the only possible way to unlock the door is to raise the stop I).

Ila ving thus described our invention, what we claim as new, and desire to secure by Letterslatent, is

1. A lock consisting, essentially, of a case having therein a horizontally-movable frame with a locking-bar formed thereon and with horizontal ribs on the sides thereof, a tumbler fixed to the lock-spindle so as to move in a recess of the frame and actuate the same, two similar disks pivoted to the lock-case on opposite sides of the frame, each of said disks having a radial slot therein to receive a rib of said frame, means for placing the slots of said disks in line with the ribs of the frame, and a stop projecting downwardly through the top of the case and upon each side of the frame, so as to cut off the slots of the disks from the ribs of the frame, substantially as described.

2. The combination, with a lock-ease, and with a locking-bar movable horizontally in said case and having a recess in the upper part thereof, of a vertically-movable stop projecting through the case into the recess of the locking-bar, so as to limit the movement of said bar, substantially as described.

3. The combination of the ease, the movable frame having longitudinal ribs, the revoluble disks having slots to receive the ribs, and the forked stop mounted in the case to slide between the ribs and the slotted disks, substantially as described.

4. The combination, with the case A and frame B, having tumbler C for actuating the same, and having the recess B therein and the ribs B thereon, of the disks 1) D, pivoted to the case A. having slots 0 therein, and having a catch a, pin y, and pins (Z and f to bring the slots in line with the ribs B and the stop I) for cutting off the disks from the ribs, substantially as described.
